FRANCESCO CONIGLIO, OF NEW YORK, N. 'Y., ASSIGNOR 0F ONE-HALF TO JEBARD B. MARSICO, OF BROOKLYN, NEW YORK.

HORSESHOE.

To all whom it may concern:

Be it known that I, FRANCESCO CoNIGLio, a subject of the King of Italy, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to horseshoes and particularly to detachable calks therefor and it has for its principal object the provision of a sectional calk for the toe end or portion of the shoe, the sections being arranged relatively whereby they are normally continued into one another so as to form a substantially continuous or uninterrupted tread surface at the toe of the shoe and yet designed and arranged whereby a particular section may be expeditiously removed when worn and a new section substituted therefor at a minimum cost.

A still further object of the invention resides in the construction of a sectional toe calk wherein such mutual or mating relation is set up between the adjacent sections as to permit the structure to effectually withstand all ordinary strains which are commonly applied to this part of the shoe. Another object of the invention resides in the construction of a shoe in which the side branches thereof may be adjusted relatively in order that the shoe may be made to properly accommodate itself to the hoof of the animal, and in view thereof, I contemplate providing a toe calk consisting of sections which are capable of accommodating themselves to the mentioned adjustment of the said branch portions of the shoe.

In the drawings forming a part of this specification and in which like reference numerals indicate similar parts throughout the several views :Figure l is a bottom plan view of the shoe. 7 Fig. 2 is a front end view thereof. Fig. 8 is a section on the line 3-3-of Fig. 1. Fig. 4 is a perspective view of the companion sections of the toe calk. Fig. 5 is a view similar to Fig. 1 of a portion of the shoe showing a slightly modified form of the invention. Fig. 6 is a side view thereof. Fig. 7 is a perspective view of one of the heel calks in the modified form of the invention. Fig. 8 is a similar VIEW of the other toe calk in the modified form of the invention.

Serial No. 66,809.

The invention, as shown in Figs. 1 to 4L inclusive of the drawings comprises, a shoe wherein the toe portion thereof is provided with angularly disposed longitudinal dovetailed grooves 11, which open at their forward ends onto the front edge of the shoe, while, at the rear the said grooves open directly onto stops 2 which are formed as an integral part of said shoe. The said grooves l-1 are intercepted by transverse passages 8, whose outer ends also open onto the forward edge of the shoe.

The toe calk, which is accommodated in the grooves l-l, consists of mating sections 4 and 5, each having a base rib 6 which is freely slidable in its receiving groove 1. The section 5 of the toe calk is somewhat smaller than the section 4 and as illustrated, it is provided with an angular surface 7 which is adapted to come in mutual contact with a similar surface 8 on the mating section 4; of the calk. The said surface 7 of the section 5 is disposed in parallel relation to that groove 1 of the shoe, which accommodates the section l, and incident to the fact that the section 5 is smaller than the next adjacent section 4:, it follows, that when the former is applied, sufiicient space is formed at one side thereof whereby to permit the section a to be freely adjusted into the receiving groove 1. When applied, the rear faces of the sections 4 and 5 come in contact with the stop lugs or shoulders 2 and they are effectually braced thereby and in addition thereto accuracy in effecting alinement of the passages 3 with similar passages 9 inthe calk section is insured in order that the alined passages may properly accommodate fastening keys or screws 10. These keys are adapted to be inserted in the passages from the front of the shoe as illustrated, the opposite ends of the keys are split and they are adapted to be spread and operatively extended into receiving recesses 11 on the inner face of the shoe. In this manner, the sections 4: and 5 are securely held in their intended positions upon the toe portion of the shoe as will be fully understood. Through the fact that thesurfaces 7 and 8 come in mutual con tact with each other, the sections 4 and 5 are satisfactorily braced and held against being unduly deranged by such strains verse, key passage 15 and a stop lug 16, the,

latter being disposed directly at the forward end of the mentioned groove 14 whereby to permit of the abutment thereagainst of the forward face of a heel calk 18, the latter having a dovetailed rib 19 which is slidably fitted in the groove 14:- This ribis also provided with a key passage 20 which alines with the key passage 15 whereby they may both receive a locking key 21.

In the form of the invention shown in Figs. t to 8 inclusive of the drawings, the toe calk consists of mating sections 22 and 23 which are similar to the toe calk sections in the first embodiment of the invention. This calk is designed for winter use and each section is provided with a relatively sharp arcuate gripping surface 24, the surface 24 of one section being extended into the surface 24 of the next adjacent section as clearly shown in Fig. 5. The two sections, when combined with each other thus provide a. traction surface uniformly curved relatively of the longitudinal center of the shoe whereby to maximize the gripping action of the shoe against the roadway as will be understood. The heel calks 26 and 27 which are adapted to be fitted to the heel ends of the shoe in a fashion identical with that described in the first embodiment of the invention, are each of a similar design and they are provided with a relatively sharp gripping or traction edge or surface 28, the surface or edge 28 of one of said calks being extended at right angles to the edge 28 of the other calk.

In either of the forms of the invention, the calks may be expeditiously removed when worn and replaced by new calks at a minimum cost. The construction is such that the sides of the shoe may be adjusted relatively at the time of fitting the shoe to the hoof of the animal. It is also desired to make mention of the arrangement of the calks whereby the shoe in its entirety will be nicely balanced or the weight evenly distributed.

What is claimed as new is 1. A horseshoe having a kerf provided with a horizontal branch disposed in line with the axial center of the shoe and located upon the under side of the shoe at the toe end thereof and provided with a vertical branch opening onto the inner surface of the toe end of the shoe, and a calk detachably connected with the toe end of the shoe and consisting of sections mutually abutting one another at a point approximately in vertical alinement with the kerf.

2. A horseshoe having a kerf provided with a horizontal branch disposed in line with the axial center of the shoe and located upon the under side of the shoe at the toe end thereof and provided with a vertical branch opening onto the inner surface of the toe end of the shoe, a calk detachably connected with the toe end of the shoe and consisting of sections mutually abutting one another at a point approximately in vertical alinement with the kerf, means on the toe portion of theshoe for slidably accommodating the calk sections, and means on the shoe for limiting the sliding movements of said calk sections.

3. A horseshoe having a kerf provided with a horizontal branch disposed in line with the axial center of the shoe and located upon the under side of the shoe at the toe end thereof and provided with a vertical branch opening onto the inner surface ofthe toe end of the shoe, a calk detachably connected with the toe end of the shoe and consisting of sections mutually abutting one another at a point approximately in vertical alinement with the kerf, means on the toe portion of the shoe for slidably accommodating the calk sections, means on the shoe for limiting the sliding movements of said calk sections, and retaining devices for securing the calk sections against said second means.

4. A horseshoe having a sectional toe calk, the said sections having surfaces normally in mutual contact with each other along an angle intercepted by a line drawn through the longitudinal axis of the shoe, the said shoe having a weakened portion at its toe end to permit of slight relative separation of said normally contacting surfaces when the sides of the shoe are moved relatively, as-and for the purpose specified.

5. A horseshoe having angularly disposed grooves,v a toe calk consisting of sections having portions fitting in said grooves, the said sections having angularly disposed surfaces mutually contacting with each other,

the angular surface of one sectionbeing disposed in parallel relation to the groove in the shoe which receives the next adjacent section.

' 6. A horseshoe having'its toe end weakened respectively on horizontal and vertical lines, and a sectional calk detachably connected with the toe end of the shoe and having surfaces normally contacting with each other on a line intercepting the horimeans for securing said sections in fixed pozontally weakened portion of the shoe. sition upon said shoe. 1
